Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
